A new perspective on bond analytics

A clearer view
of fixed income.

Behind every bond is a relationship between price, yield, and risk. Convexity Cubed brings that relationship into focus.

Three dimensions.
One connected view.

Built around the fundamentals

Fixed income is complex.
Understanding it should be clearer.

01

Valuation & yield

Start with the cash flows. Understand how a bond’s price connects to its yield, timing, and underlying assumptions.

02

Duration & convexity

Look beyond a single number. Explore sensitivity to interest rates and the curvature that a linear estimate can miss.

03

Scenarios & perspective

Ask what changes when markets move. Connect assumptions to outcomes to see the shape of fixed-income risk.

Go beyond the straight line

The curve
changes the story.

A bond’s price doesn’t move in a straight line as yields change. Convexity captures that curvature—and helps explain what duration alone leaves out.

Move the yield. See the relationship.
